This user guide introduces the features and usage of the Rotronic AG HygroClip 2 (HC2) humidity temperature probes.
The HC2 series are digital humidity-temperature probes based on AirChip 3000 technology, featuring a UART serial interface and two 0...1 V linear analog output signals. They are designed for use with Rotronic humidity-temperature instruments such as hand-held indicators, data loggers, and transmitters, though they can also operate as standalone devices. The probes support user-configurable settings, dew point calculation, and automatic sensor testing.
